Os tratamentos foram dispostos em delineamento em blocos casualizados usando arranjo fatorial 3 × 2, referente as doses de calcário de 1,4; 2,5 e 3,6 t ha-1, 80 e 160 kg ha-1 de K2O na forma de cloreto de potássio. Pelos resultados, a irrigação com água salina (3,6 dS m-1), em comparação com dados da literatura de plantas irrigadas com água de boa qualidade, não comprometeu a capacidade produtiva do maracujazeiro amarelo. Dentre os tratamentos, a combinação de 80 kg ha-1 de K2O com 3,6 t ha-1 de calcário calcítico proporcionou os maiores valores de massa média dos frutos, produção por planta e produtividade da cultura. Apesar da alta salinidade da água de irrigação elevar o caráter salino do solo no ambiente radicular das plantas durante o período da estiagem, as águas do período chuvoso e as condições físicas do solo proporcionam a lixiviação dos sais e possibilitam o uso de água com restrições salinas na agricultura.

YELLOW PASSION FRUIT PLANTS PRODUCTION ON SOIL WITH LIME AND POTASSIUM UNDER IRRIGATION WITH SALINE WATER 2 ABSTRACT The experiment was carried out in Coronel Ezequiel county, Rio Grande do Norte, Brazil, in order to evaluate the effects of limestone and chloride potassium in production components of yellow passion fruit plants and soil salinity, caused by irrigation with saline water of 3.6 dS m-1 during the dry season, and salt leaching of the soil promoted by waters of the rainy season. Treatments were arranged in randomized blocks using factorial design of 3 × 2, referring to three levels of limestone, 1.4, 2.5 and 3.6 t ha-1 and two potassium levels, 80 and 160 kg ha-1 in potassium chloride form. According to present results, irrigation with saline water (3.6 dS m-1), in comparison with data from the literature about plants irrigated with non-saline water, did no compromise the productive capacity of yellow passion fruit. Among the treatments, the combination of 80 kg ha-1 of K2O with 3.6 t ha-1 of limestone provided the fruits production with more mean mass, yield per plant and crop yield. Although the high salinity of the irrigation water increases the soil saline character on root environment of the plants during the dry season, the rainy season waters and the soil physical conditions provide the salt leaching and allow the use of water with saline restrictions in agriculture.

The research had as objective to study the influence of the doses of nitrogen, phosphorus and potassium on soil fertility and nutritional status of yellow passion fruit plants. The experimental design was in randomized blocks in an incomplete fractioned factorial 1/2 (4 × 4 × 4), with four doses of N (150, 300, 600 and 1200 Kg-1 ha-1 yr-1 N); four doses of P2O5 (200, 400, 800 and 1600 kg-1 ha-1 yr-1) and four doses of K2O (100, 300, 500 and 700 kg-1 ha-1 yr-1). The fertilizers used were the ammonium nitrate = 32% N; triple superphosphate = 44% P2O5 and potassium chloride = 60% K2O. In the fertility of the nitrogen fertilization increased the content of phosphorus and sulfur. The doses of P2O5 increased the concentration of P in the soil. The doses of K2O influenced the increase in the content of K in the soil in the harvest 2013/2014. There was an interaction of the doses of N and K2O in the availability of K in the soil in the harvest 2012/13 with the maximum levels of K, in the doses of 200-400 kg N ha-1 and 600 to 700 kg ha-1 of K2O. In the nutritional state the yellow passion fruit plants was influenced by the doses of N for the sulfur content of the leaves. The maximum content of S leaf concentration of 3.63 g kg-1 was obtained in the dose estimated at 1120 kg ha-1 of P2O5.

We report the use of the coat protein (CP) gene from Passion fruit woodiness virus (PWV) to produce resistant transgenic plants of yellow passion fruit. A full-length CP gene from a severe PWV isolate from the state of São Paulo, Brazil (PWV-SP) was cloned into pCAMBIA 2300 binary vector, which was further introduced into Agrobacterium tumefaciens strain EHA 105. Leaf disks were used as explants for transformation assays, e.g., 2,700 and 2,730 disks excised from plants from the Brazilian cultivars IAC-275 and IAC-277, respectively. In vitro selection was performed in kanamycin. After transferring to the elongation medium, 119 and 109 plantlets of IAC-275 and IAC-277, respectively, were recovered. Integration of the PWV CP gene was confirmed in seven of eight plants evaluated by Southern blot analysis, showing different numbers of insertional events for the CP gene. Three transgenic plants (T3, T4, and T7) expressed the expected transcript, but the 32 kDa PWV CP was detected by Western blot in only two plants (T3 and T4). The results of three successive mechanical inoculations against the transgenic plants using three PWV isolates showed that the primary transformant T2 of IAC-277 was immune to all isolates.
